[QUOTE="vancewalker007, post: 2021094, member: 66917"] You're going to experience a barrel speed-up once you get somewhere between 150-250 rounds through the barrel. I wouldn't worry too much about the velocities you are seeing now. I would suspect you will get that 156 up into the mid 2900s once that speed up hits with RL26 or H1000 and the 140 up around 3000. My 26in tube hits 3040fps with the 156 easy with no pressure using H1000. Typically this cartridge drops around 50fps per inch of barrel. This has been born out with Gunwerks tests on the PRC along with other popular hunting cartridges. Keep tracking your velocities so you can detect the barrel speed-up because it will effect your ballistic corrections for target/hunting and your POI. [/QUOTE]
